I was prepping pre-game last week and working on fair catches. During that process I got to thinking about how tack-on might apply in some of these situations.
A play I was thinking about.
R1 calls for a fair catch of a scrimmage kick. K2 is covering the kick and gets close to R1 such that the ball hits K2's helmet and rebounds toward K's goal. K2 did not give R1 an opportunity to catch the kick. R3 picks up the ball and runs for another distance where he is tackled. A flag for fair catch interference is thrown.
So this is a K foul during a kick so we'd tack-on from the succeeding spot. Does the awarded fair catch still exist?
